Taming Quantum Causality


Taming Quantum Causality (TaQC) is an ANR project (ANR-22-CE47-0012) that started in 2023 for 4 years, and joining together members from Inria Lyon, Institut Néel, CEA Larsim, and Laboratoire Méthodes Formelles.

The project aims at better understanding and harnessing the power of indefinite causal orders, a phenomenon allowed by Quantum advantages in quantum technological protocols arise from the use of non-classical resources, e.g., superposition or entanglement. The discipline of quantum information has recently come to realise that quantum advantages can also be obtained via another fundamental physical principle: causality. The project aims at carrying out fundamental research to develop quantum causality as a new non-classical resource on par with superposition and entanglement. This will allow for a new approach to quantum computing, suggesting new ways of thinking and devising quantum circuits, based on new concepts, and opening the door to new applications for quantum information processing.
